A source who used to work on mobile projects for Google recently
told us that the company viewed Slide as a pure talent
acquisition for Google+, the Facebook competitor that Google launched
earlier this summer.

Now, Google will gradually phase all the Slide projects out.

It's a fizzling end for a company that was once valued at over
$500 million, but Levchin remains chairman of the board at
Yelp and an active angel investor.
